Evaluation of Active Photovoltaic Array Based on PSIM Software in Actual Scale

Photovoltaic (PV) power generation systems are often affected by the external environment (animals, plants, or buildings, etc.) during operation, causing the problem of partial shadowing of the PV array. In the case of partial shadows, conventional photovoltaic array connection and control methods cannot guarantee that each panel works at maximum power. In response to the above-mentioned situation of PV arrays in practical applications, this paper proposes a novel active PV array (APV) to control each PV panel to operate in the optimal state. Through the PSIM simulation analysis of the actual PV power station situation, the effectiveness of this control method is verified.
